PhD Scholarship in Environmental Science Focusing on Effects of Chemical Mixtures on Microbial Functions

A PhD scholarship in environmental sciences is available at Stockholm University. This position is available for four years. The deadline for applying is November 27, 2018.

The department has about 220 employees of which about 60 PhD students. Research study programs are offered in environmental science, analytical chemistry and environmental chemistry and courses are given in environmental science and analytical chemistry.

Project description

This PHD position is one of 13 offered at 8 Universities within the new EU-funded ECORISK2050 Innovative Training Network (ITN). The ECORISK2050 project will evaluate the effects of global change on the use and emissions of chemicals, their transport and fate in agricultural and urban environments, their ecotoxicity and risks to aquatic organisms, and how these risks can be mitigated. The specific objective of this PHD position is to use the concept of chemical activity to assess effects of chemical mixtures on environmental systems. To do this we will use microbial communities as model systems. The PHD student will perform laboratory experiments with sediment spiked with chemical mixtures of various chemical activities to test hypotheses related to how microbial communities and their functions respond to chemical pollution, expressed as chemical activity. The PHD student will spend 2 months on secondments to IMDEA Agua foundation in Spain to learn about aquatic ecotoxicology and ecological risk assessment in Southern European conditions, and 2 months to the Norwegian Institute for Water Research (NIVA) to learn about and apply Bayesian network modeling on effects of chemical mixtures on microbial communities and functions.

Qualification requirements

To meet the general entry requirements, the applicant must have completed a second-cycle degree, completed courses equivalent to at least 240 higher education credits, of which 60 credits must be in the second cycle, or have otherwise acquired equivalent knowledge in Sweden or elsewhere. In order to meet the specific entry requirements, for doctoral studies in Environmental Science, at least 45 of the credits at the second cycle must be in one of the natural sciences (Biology, Chemistry, Earth Sciences, Physics, or Meteorology) including a 30 hp/HEC thesis project. The applicant should also have 30 hp/HEC in other natural science subjects different from the major.

IMPORTANT! This position is open only to individuals who have spent less than 12 months in Sweden in the last three years. Applicants must also be in the first four years (full-time equivalent) of their research careers, measured from the date when they obtained the degree that would formally entitle them to embark on a doctorate, either in the country in which the degree was obtained or in Sweden.


The selection among the eligible candidates will be based on their ability to successfully pursue the research education. Special emphasis is put on the applicant's knowledge and skills within the subject area, ability to express her/himself verbally and in writing, analytical aptitude, creativity, initiative and independence, and a capacity for working together with others. The evaluation will be made based on the relevance of past education and experience, grades from previous university courses (in particular at the advanced level), the quality and ambition of the independent project work, references, a cover letter motivating the candidate's interest, and interviews. Applications are welcome from both EU citizens and from outside the EU (subject to relevant immigration formalities). Recruitment within ECORISK2050 aims to fulfil the equal opportunity objectives of the Marie Curie programme and hence applications are welcomed from applicants regardless of gender, nationality, ethnic origin, and from individuals wishing to resume research careers after a break.

Knowledge and experience of applying concepts and methodologies in environmental chemistry and microbiology will be a strong asset.
